[ 1 ] - طراحی بهینه کنترل‌کنندۀ NL-PIDF و SMES برای کنترل بار فرکانس سیستم قدرت هیبریدی غیرخطی با استفاده از الگوریتم کریل‌ها
در این مقاله مسئلۀ پایداری فرکانس در سیستم قدرت سه‌ناحیه‌ای با توربین‌های بخاری و گازی با در نظر گرفتن قیود غیرخطی ناشی از واحد بازگرمکن توربین بخار، محدودیت میزان تولید (GRC)، باند مرده گاورنر (GDB) و الگوی دینامیکی دیگ بخار (BD) بررسی شده‌اند. برای کنترل بار فرکانس، سیستم قدرت کنترل‌کنندۀ جدیدی به‌صورت تناسبی – انتگرال‌گیر – مشتق‌گیر - فیلتر نویزگیر غیرخطی (NL-PIDF) معرفی و بهینه شده است. برا...
[ 2 ] - A Soft Switched DC-DC Boost Converter for Use in Grid Connected Inverters
This paper presents a soft-switching DC-DC boost converter, which can be utilized in renewable energy systems such as photovoltaic array, and wind turbine connections to infinite bus of a big power network, using grid connected inverters. In the proposed topology for the DC-DC boost converter, the main and the auxiliary power switches are turned on and turned off with zero voltage switching (ZV...
[ 3 ] - Voltage Flicker Parameters Estimation Using Shuffled Frog Leaping Algorithm and Imperialistic Competitive Algorithm
Measurement of magnitude and frequency of the voltage flicker is very important for monitoring andcontrolling voltage flicker efficiently to improve the network power quality. This paper presents twonew methods for measurement of flicker signal parameters using Shuffled Frog Leaping Algorithm(SFLA) and Imperialist Competitive Algorithm (ICA).

[ 4 ] - Residential Load Manageability Factor Analyses by Load Sensitivity Affected by Temperature
Load side management is the basic and significant principle to keeping the balance between generation side and consumption side of electrical power energy. Load side management on typical medium voltage feeder is the power energy consumption control of connected loads with variation of essential parameters that loads do reaction to their variation. Knowing amount of load's reaction to each para...
[ 5 ] - Modeling, Simulation and Control of Matrix Convert for Variable Speed Wind Turbine System
This paper presents modeling, simulation and control of matrix converter (MC) for variable speed wind turbine (VSWT) system including permanent magnet synchronous generator (PMSG). At a given wind velocity, the power available from a wind turbine is a function of its shaft speed. In order to track maximum power, the MC adjusts the PMSG shaft speed.The proposed control system allowing independen...
[ 6 ] - Electrical Load Manageability Factor analyses by Artificial Neural Network Training
On typical medium voltage feeder, Load side management means power energy consumption controlling at connected loads. Each load has various amount of reaction to essential parameters variation that collection of these reactions is mentioned feeder behavior to each parameter variation. Temperature, humidity, and energy pricing variation or major event happening and power utility announcing to th...
